![]() The OS in the host computer is the Ubuntu 20.04.2 LTS, kernel Linux 5.4.0-67-generic x86_64.Ģ. Hardware installation for HDDSuperClone and R-Studio Click image to enlarge If the source drive is small, it's possible to use a disk image file rather than another hard drive. Connect the source drive and the target drive if such drive is necessary. The course of the required actions is the following:ġ. We'll try to recover data from a faulty drive (Seagate ST380817AS) that cannot be processed directly because of its poor conditions. This article will show you how R-Studio can work together with the HDDSuperClone in this mode. This is especially important when the disk is malfunctioning or dying. This mode greatly reduces tear and wear of the source disk. ![]() When the same data is accesses next time, HDDSuperClone takes the data from the target disk/image rather than from the source disk. When a program accesses some data on that virtual drive, HDDSuperClone also copies that data to the target disk/image file. The main advantage of this mode is the partial imaging of the source drive. The HDDSuperClone driver uses all advanced methods to extract data from the problematic disk, but this is not all. This virtual drive becomes accessible to the host OS and other programs. A virtual drive mode (the commercial version only): In this mode, HDDSuperClone installs a special driver that creates a virtual drive from the disk. This mode is available in both free and commercial versions, with some small limitations for the former.Ģ. Such data may be processed by a third-party data recovery program. It also creates a disk map file (the log) that specifies the sectors that cannot be read (the bad sectors). The disk cloning/imaging mode: It simply copies data from one disk (the source) to another disk or a file (the target). ![]() It uses several advanced techniques to extract data from hard drives with bad sectors and other hardware issues while doing everything possible to avoid inflicting even more damage on the drive being processed.ġ. It's specifically designed to work with unstable, faulty, or dying hard drives. HDDSuperClone from SD Computing Service is a software solution for disk imaging, cloning, and data extraction tasks. Usually those software solutions work under Linux, as this OS gives the most flexibility in disk operations among the major PC operating systems. Taking into account their minimal cost, it's not surprising that those software solutions are widely used. Such solutions do have some limitations compared with their hardware counterparts, but they can still solve most data extraction tasks. They use system disk I/O ports for hardware emulation, as well as their own drivers with extended controls that aren't available in standard system drivers. However, there are good substitutions for that data recovery hardware - pure software solutions. Quite often cost considerations limit the number of such devices that many small data recovery companies can afford, or, at worst, prevent them from having even one piece of such hardware. Hardware solutions have their own drawbacks, with the most important being their prices. See R-Studio help page DeepSpar Disk Imager™ and our article "Joint work of R-Studio and PC-3000 UDMA hardware" for more details. They've earned great standings in the data recovery community and are widely accepted in data recovery labs around the world, and they also work quite well with R-Studio, too. Two examples come to mind: PC-3000 from ACELab and DeepSpar Disk Imager™ from DeepSpar. Other times, faulty hard drives require specialized hardware and software to implement a solution. There are some methods to get around this, like skipping some sectors in the hope that the next sectors will be readable, but they are not implemented into the standard disk drivers. For example, every time the system runs into bad sectors on the hard drive, the read speed drastically drops - thus making disk imaging a very long process. It's difficult to extract data from malfunctioning or dying hard drives using standard system routines.
